Despite doing the usual, sitting on side of bed. I stood up walked to window to see if it had snowed and then suddenly without warning legs gave way once then twice and next thing I know on floor. Just glad I was not on a hard surface or on stairs . Not sure if blacked out. Strong Twitching followed for half hour. I had twitching the night before too . Strange . No dizziness before or after.
First time in my life I have collapsed..
